7v Fan Mod

post #1 of 3
Thread Starter 
I recieved my new Corsair case yesterday (yay! biggrin.gif) and I was curious about the 7v fan trick to quiet my box down even further.

I get that as long as you don't try running too much current through the "7v" connection, that it -shouldn't- damage the PSU. The part that made me curious was- would a 9v mod be possible/safe with the 12v+ and 3.3v+?

You can get resistors made for that.
You have all kinds of different ones from Zalman and Nexus and they are pretty cheap to.

Check this:

There are more variations, just an example.

No need to MOD and its cheap.

Edit:
Here is how you do the 7V MOD:

Thank ya Farih, already knew how to do the 7v mod though, and my PSU didn't seem to go into any protection when I tested it. So I may stick with that, what I was more curious about was the viability of a 9v mod. Though I don't know how much outgoing current is on the 3.3v+ line and running fans back through it may shut the PSU down (or kill it).

Actually have one of those Zalman resistors around here for my old CNPS cooler, but I doubt it would survive a pair of Slipstream fans.

Wouldn't even bother with this but a slipstream fan killed one of the headers on my H80 fan controller, and 12v through that rad is loud as hell.
